Article in the New York Times -- Prognosis: In Smoking, Research Finds, Cutting Back Won’t Do, by Eric Nagourney: "Smokers who say they just can’t quit are sometimes told to at least cut down. But even if they reduce their intake by half or more, they are unlikely to see much benefit, a new study reports. . . . It is unclear why those who cut back did not seem to be healthier. One possibility, the study said, is that to compensate for the cigarettes they give up, smokers inhale smoke more deeply and smoke more of each cigarette."
